What size room does the Power Breezer H950SL cool?

13,600 BTU of real cooling (SACC) suits about 450 to 700 sq ft with normal sun and two people (about 405-630 sq ft if very sunny), by the ENERGY STAR floor-area table. Size by SACC, not the larger BTU on the box.

How many watts does the Power Breezer H950SL use, and what does it cost to run?

About 1193 watts at full power (13,600 BTU/h divided by its CEER of 11.4), roughly 10.4 amps if it runs on 115 V. At 750 hours a year and 18.0¢/kWh that is about $161, which is $35 more than the typical certified 12,000 BTU or more portable unit ($127). Its inverter compressor slows down once the room is cool, so real use is often lower. Its CEER beats 21% of the 147 certified models in its size class.

Why does the Power Breezer H950SL have two hoses?

One hose brings outdoor air in to cool the condenser, the other sends the heat out, so no cooled room air is wasted. 99% of the certified 12,000 BTU or more models have two hoses, and at 11.4 CEER this one is below their 12.8 median.

How does the Power Breezer H950SL handle the water it removes?

It collects the water in a removable bucket that you empty by hand when it fills.

Can the Power Breezer H950SL also heat the room?

No, it only cools. 33 of the 147 certified 12,000 BTU or more portable models can also heat if you want one unit for the year.

Is the Power Breezer H950SL as efficient as a window air conditioner?

No. The 47 ENERGY STAR certified window units that cool about as much (within 15% of 13,600 BTU) have a median CEER of 15.0, against 11.4 here, and the best reach 16.8. At 750 hours a year a window unit with that median would cost about $123, $39 less than this one. ENERGY STAR window units are the more efficient part of the window market, so the gap to an average window unit is smaller. A portable unit makes sense when a window unit will not fit or is not allowed.

Power Breezer H950SL

Below average efficiency for its size: a CEER of 11.4 beats 21% of the certified 12,000 BTU or more portable air conditioners.

The Power Breezer H950SL delivers 13,600 BTU of real cooling (SACC), enough for about 450-700 sq ft, draws about 1193 watts and costs about $161 a year to run at typical U.S. use and prices. A window unit that cools as much costs about $123 a year.

Design: Two hoses Draws outdoor air for its condenser

A good fit if…

You want the better cooling design - with two hoses it does not pull warm outdoor air into the room to replace what it exhausts.
You want steadier, quieter running - its variable-speed compressor slows down instead of cycling.

Think twice if…

Running cost matters most - its CEER is below average for 12,000 BTU or more portable air conditioners.
You also need heat - it cools only.
You want no drain to deal with - it uses a bucket you must empty.
You have limited space - units this size are the largest and heaviest portable air conditioners.

These model numbers are certified with the same capacity, efficiency, hose design, heating, drain type and compressor as the Power Breezer H950SL.They may be the same unit sold under several brands, or different products that test the same: the DOE data has no dimensions or noise figures, so check those with the maker. Ratings within about 2% in capacity and 0.3 in CEER are treated as the same; a model whose own rating differs a little shows it in brackets.
